RUBBER HEEL.

Application filed May 13, 1927. Serial No. 191,015.

- ber heel.

Another object of the invention is to provide a heel of this nature witha chamber having a resilient cushion therein, adapted when the heel issecured to the shoe to en hence its springiness.

A further object of the invention is to provide a heel of this naturewith a chamber adapted to contain a spirally wound inflated tube forminga cushion to enhance the clasticity of the said heel.

Other objects and novel features ofthe invention will become moreapparent as the specification proceeds.

I11 the drawings forming a part of this specification Figure 1 is aperspective view of a shoe with my improved heel attached thereto.

Fig. 2 is a fragmental longitudinal sectional view of the heel end ofthe shoe, showing one embodiment of my invention.

Fig. 3 is a top plan view of my improved heel and Fig. 4 is alongitudinal sectional view of my improved heel taken on line 44@, Fig.3 with the cushion indicated in dot and dash lines.

Referring to the drawings in detail in which like numerals refer to thesame parts throughout the various views, 5 indicates a shoe providedwith the usual sole 6 and leather heel 7. Secured to the leather heel 7is a heel 8 preferably made of rubber and provided approximately at thecenter thereof with a chamber 9 open at the top surface 10 of the saidheel 8. An inflated cushion or pad 11 preferably made of soft rubbertubing is glued to or otherwise secured in the said chamber 9. The saidpad 11 as already stated may be made of inflated rubber tubing, woundspirally and closed at its ends 12 and 13 either by gluing or in anyother suitable manner. Glue is applied along the entire length on oneside of the tube as at 14, so that when it is spirally wound the gluewill prevent the spreading of the spiral and maintain same in requiredshape.

The pad 11 projects above the top surface 10 of the rubber heel and whenthe said heel 8 is nailed to the shoe a hollow or concave space 15 isformed between the leather heel portion 7 and the said rubber heelportion 8 which permits of a great amount of resiliency or spring actionbetween the heel sections 7 and 8. The rubber heel is secured to theshoe by nails 16 passing through the usual holes or openings 17 into theheel 7.

It will be readily seen that with my improved heel a great amount ofresiliency is obtained regardless of the quality of rubber used in themanufacture of the heel, as there is always present a highly resilientcushion between the leather and rubber heels 7 and 8 respectively.

lVhile I have shown a single cushion centrally located on the rubberheel, I do not limit myself to this exact construction as a plurality ofsuch cushions may be provided and spaced as may be desired. Nor do Ilimit myself to a pad or cushion made of rubber tubing as manyvariations in the construction of the pad and general arrangement of thevarious portions of my invention may be had without departing from thescope of the appended claim.

Having described my invention, what I claimas new and desire to secureby Letters Patent isr A rubber heel provided with a chamber therein,open at the top surfacethereof and an inflated spirally wound tubularcushion secured in the said chamber projecting above the top surface ofthe heel.
